WINDOW-FRAME.

Speccaton of Letters Patent No. 15,000, dated June 3, 1856.

To all whom t may concern.'

Be it known that I, JOHN CASEY, of the city, county, and State of New York, have invented a new and useful Improvement in Tindow-Frames, whereby the Sashes May be Detached Therefrom IVithout- Removing the Beads from the Frames; and I do hereby declare that the following is a lfull, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a face view of a window frame one side of which is bisected and showing` my improvement. Fig. 9 is a transverse section of ditto (fr) Fig. l showing the plane of section. Fig. 3, is a horizontal section of ditto (y) Fig. l, showing the plane of section.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in having a portion of one of the side pieces or stiles of the frame or casing movable and arranged as will be presently shown and described so that bo-th sashes may be removed from the frame or casing without detaching the beads therefrom.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a window frame or casing having pockets at each side of it to receive sash weights which are attached to the sashes B B by cords (a). The cords are attached to the sashes by having knots or balls (b) on their ends, said knots or balls being fitted in slots or grooves (c) in the upper part of each sash at each side. The cords (a) work over pulleys (d) in the upper ends of the stiles or side pieces (e) (f) of the frame or casing. The stiles or side pieces (e) of the frame or casing have the usual parting bead (g) fitted in them to form the grooves, one for each sash, one of the stiles (e) has a section of it C, made detached from the other part, the section or part C extends some distance above the lower sash B and it embraces a portion of the parting bead (g) the part C does not extend entirely across the stile but merely takes in the parting bead, the part C is so arranged that it may be shoved bodily back within the socket by having curved slots (h) made in its upper and lower sides in which lugs (i) attached to the stile fits so that when the part C is shoved back within the pocket it may, when relieved of the pressure or force which attached it return in proper place by its own gravity.

When the part C of the stile is in proper position or flush with the other part, the two sashes may be raised and lowered as usual the operation being precisely the same as the ordinary windows, the sashes of which are pro-vided withweights.

In order to detach the sashes from the frame or casing all that is required is to press the lower sash B laterally or sidewise so thatI the side of the sash will press inward the part C of the stile. By doing this the opposite side of the sash may be brought out free from the bead on the opposite stile and the lower sash will be consequently detached from the frame or casing, the cords (a) are then detached from the sash by withdrawing the kno-ts or balls (a) from the grooves or slots (c) said knots or balls being then fitted in grooves or slots in the stiles (e) (f) so that the weights may be retained, see red lines Figs. l and 2. To detach the upper sash B', it is broughtdown to the lower part of the frame or casing the part C presses back by the hand and the sash is then removed or detached in the same way as the lower sash just described.

The above invention is extremely simple and allows the sashes to be detached from the frame or casing with the greatest facility so that incase of washing, glazing, or painting, the work may be done conveniently and better done than if the sashes were in the 'frames or casing.

lVindow frames or casings as at present constructed do not allow the sashes to be readily removed from them, the beads require to be taken 0H, and this is attended with considerable trouble, so much so, that the sashes are rarely removed from the frames while the work above mentioned is performed.

I do not claim having a portion of one of the stiles made adjustable or movable irrespective ot the arrangement of the same, or the manner in which said portion is operated; but

What I d0 Claim as new and desire to whereby the part or portioh, C, sl rendered secure by Letters Patent, s, adjustable, as shown, for the purpose speci- Havng the portion, C, of one O the fied.
